摘要：

Animal models of child neglect (known as maternal separation or early deprivation) have suggested a causal link to subsequent depression and/or anxiety in children. In this experiment, the acoustical features of the ultrasonic calls emitted by a rat pup when separated from its dam were analyzed as well as the maternal behavior when the dam was allowed to retrieve the pup. Bout structure and harmonic double shifts did differ between controls and "neglected" pups, as did maternal attention. This model will be used to determine neural mechanisms underlying deficits in attachment behavior.
